Default IntroJucer AU plug for ppc crashes

Audio Plugins
1

Hi,

building an IntroJucer AU plug for ppc with the default source. It crashes consistently on a G5 with 10.5.8 OS installed. The base SDK is 10.6 and the target OS is 10.5.

This is the top of the crash report:

Any ideas? I can’t debug on this machine because it has 10.5 and the base SDK is 10.6.

Update:

building against the 10.5 base SDK seems to fix the problem. I need 10.6 though…

Fixed the problem by specifying base SDK 10.5 for ppc and 10.6 for the other platforms

Thanks PieterS, we’ve had the exact same problem and your solution worked for us.

We had an additional related problem which others may face, as we use OpenGL and juce now uses OpenGL 3.0 functions which aren’t available on powerpc. We solved it for now by #if-ing those out (see https://github.com/yairchu/juce/commit/a79d7610ea311e39136e2234da28eeb678498a82) as our apps don’t need that specific OpenGL functionality (OpenGL component sharing its rect with other components).

Cheers!

Did anybody succeed in building the latest tips demo plugin using 10.6 as base SDK? If I use 10.7 as base SDK and 10.5 as development target, the plugin crashes validation on 10.5 with the same error as in the OP…

The functions at the top of the stack in that crash are in Apple’s AU cpp files, which have changed over the years (and which normally need patching just to get them to compile at all). If you’re building with the newer SDK, it might be worth checking that you’ve got the latest version of those Apple files too.

I guess I have them… downloaded the newest XCode and the newest CoreAudio files, same error. It’s not such a terrible issue, people will move away from 10.5 anyway, but it’s annoying nevertheless.
